🛠️ What’s in the Kit?

  • CNC-machined stainless steel sleeve

  • Oversized clutch release bearing (sleeve-specific)

  • Bearing clip

  • Hardware

  • High-temp specialty grease

  • Detailed installation instructions

⚠️ Important: The included bearing clip must be used. Omission will void the warranty and may result in premature failure.

🔧 Symptoms Fixed by the TSK61 Kit

  • Clutch chatter or shudder

  • Excessive noise during clutch operation

  • Sticky or stiff clutch pedal

  • Rough or inconsistent pedal feel

  • Premature wear or failure of clutch components

  • Surface wear on the aluminum transmission case extension

⚠️ The Problem with OEM Design

GM and Isuzu's cast aluminum bellhousing extensions are prone to damage at the clutch release bearing contact point. Over time, this results in:

  • Scored aluminum sleeve surfaces

  • Clutch misalignment

  • Transmission vibration and recurring component failure

The TSK61 provides a true upgrade, not just a temporary fix:

  • 🛡️ Durable stainless steel sleeve eliminates wear points

  • 🚫 Prevents future clutch/transmission failure

  • 🔧 Installs quickly with no case modifications

  • ⏳ Extends the life of the clutch and gearbox

  • ♻️ Fully serviceable and reversible
